Abstract
The invention concerns a method for separating from a mixture two optical isomers using a simulated moving bed including an assembly of columns divided into at least three successive zones. The amount of charge injected is greater than that of the state of a predetermined reference state. The discharge flow is greater than that of the predetermined reference state if it is required at least to preserve the purity of the less immobilized enantiomer. The discharge flow is less than that of the reference state if it is required to preserve the purity of the more immobilized enantiomer.
